This guide describes how to use the BP-1 battery pack with any of the DAQPad Series DAQ
units. The BP-1 battery pack is a portable power supply for the DAQPad Series units.
Introduction
The BP-1 is a rechargeable battery pack that you can use to power any of the DAQPad Series
DAQ units instead of the A/C power supply adapter that is in the DAQPad unit kit.
The BP-1 battery pack contains a 12 V sealed lead-acid battery and a solid-state dual-stage
charger for recharging. You can use the Velcro strap that is in the kit to strap the battery pack
and a DAQPad unit together to facilitate carrying and stacking them.
You cannot simultaneously charge the battery pack and power a DAQPad unit using the supplied
charger. However, in a standby application, you can use the SCXI-1383 power supply and float
charger to simultaneously charge the battery pack and power the DAQPad unit.
What Your Kit Should Contain
There are two versions of the BP-1 battery pack kit. Each kit has a different wall-mount battery
charger: one charger is for 120 VAC; the other is for 230 VAC. In addition to the battery
charger, each version of the BP-1 kit contains the BP-1 battery pack, a Velcro strap, and the BP-
1 Battery Pack Installation Guide. If your kit is missing any of the components or if you
received the wrong version, contact National Instruments.
Detailed specifications of the BP-1 battery pack are in the Specifications section of this guide.
Recharging the BP-1 Battery Pack
Warning:
Charge the BP-1 battery pack only with the enclosed battery charger. National
Instruments is NOT liable for any damage or injuries resulting from charging the
BP-1 battery pack with any other battery charger or from using the enclosed
battery charger in any other application.
